Make require_root option not to require existence of run

[Jerry1144]

I find name+require_root perfect in "tool provides a system Daemon, and a ready-made plist to be put into /Library/LaunchDaemons" scenario. Like this service do:

service do
  name macos: "cc.chlc.batt"
  require_root true
end

It makes brew output the right command to run in the Caveats section, without the "or if you want to run it once, run [the run command]" latter half.

==> Caveats
To start batt now and restart at startup:
  sudo brew services start [formula]

Therefore I think the audit rules should allow require_root to exist with name and without run.

brew audit currently complains that run must be defined to use methods other than name like [:require_root]. If I removed the require_root line, I'd have to ask users to ignore the subsequent non-sudo brew services start in Caveats. How weird would that sound!

This repository has no control over brew audit. This should be moved to Homebrew/brew
